Abstract

The invention discloses a clip hole structure. The clip hole structure comprises a clip installing hole into which a clip is inserted and clamped and a deforming hole or deforming holes, wherein the clip installing hole is of a rectangular structure; the clip installing hole is formed in a clip attachment piece; the deforming hole is formed in one side of a deforming direction of the clip installing hole or the deforming holes are respectively formed in two sides of the deforming direction of the clip installing hole; the deforming hole or the deforming holes is or are in a certain distance from the clip installing hole. According to the clip hole structure disclosed by the invention, double-hole structure optimization on a clip hole is adopted, and one deforming hole is additionally formed in one side of the deforming direction of the clip installing hole or two deforming holes are respectively and additionally formed in the two sides of the deforming direction of the clip installing hole, so that the problem of assembling and disassembling difficulty caused by deforming difficulty of a clip installing hole of an existing similar clip is solved, assembling and disassembling can be easier, the productivity is increased, a risk that one product is scrapped together with the other one because the two products in which the clip and the clip hole are arranged cannot be separated due to disassembling difficulty can be reduced, and the recovery rate of the products is increased; meanwhile, the products are lighter because certain materials are reduced, and the cost is saved.

Description

Clamp pore structure

Technical field

The present invention relates to clamp technical field, be specifically related to a kind of clamp hole with distortion hole.

Background technology

At present, existing clamp buckle structure ( as Fig. 1), clamp 3 is made up of the clamp head 31 of sphenoid structure and the clamp wall 32 under it, clamp hole only has the clamp mounting hole 4 of a rectangular configuration, when clamp head 31 inserts clamp mounting hole 4, clamp mounting hole 4 broadens by clamp head 31, by rear, clamp mounting hole 4 resiles.There is following problem when dismantling in existing clamp buckle structure: because clamp hole only has a clamp mounting hole 4, it is all enclosed construction around clamp mounting hole 4, it is more difficult that clamp mounting hole 4 is out of shape, when causing clamp 3 to assemble, contact engaging and separating force is larger, very difficult during dismounting, easily there is the damage of rupturing, being out of shape.Conforming product rate only about 88%.

Summary of the invention

The technical problem to be solved in the present invention is: when existing buckle structure causes clamp 3 to assemble, contact engaging and separating force is comparatively large, very difficult during dismounting, easily occurs rupturing, the problem of the damage of distortion.

To achieve the above object of the invention, the technical solution adopted in the present invention is: provide a kind of clamp pore structure, comprise and insert and block the clamp mounting hole of the rectangular configuration of clamp, clamp mounting hole is arranged on clamp attachment, it is characterized in that: also comprise and be arranged on clamp mounting hole deformation direction side or be separately positioned on clamp mounting hole deformation direction both sides, distortion hole at regular intervals with clamp mounting hole tool.

The rectangular opening that described distortion Kong Weiyu clamp mounting hole is parallel.

Detailed description of the invention

as Fig. 2clamp pore structure, comprise and insert and block the clamp mounting hole 4 of the rectangular configuration of clamp 3, clamp mounting hole 4 is arranged on clamp attachment 1.Compared with existing clamp pore structure, this clamp pore structure also comprises the clamp mounting hole 4 deformation direction both sides being arranged on clamp mounting hole 4 deformation direction side, distortion hole 5 at regular intervals with clamp mounting hole 4 tool, called after in the present invention of this spacing.Certainly, if needed, such as material is comparatively hard, and when deflection is inadequate, respectively arranging a distortion hole 5 respectively in clamp mounting hole 4 deformation direction both sides is also feasible.

The deformation direction of clamp mounting hole 4 is its money direction.

In the present embodiment, described distortion hole 5 is the rectangular opening parallel with clamp mounting hole 4.

as Fig. 3 and 4, the mounting hole attachment 2 in this example and clamp attachment 1 and be respectively automobile front beam grid body and grid related parts, be PP material, between the thick 2mm to 3.5mm of body material.Clamp is made up of the clamp head 31 of sphenoid structure and the clamp wall 32 under it, and clamp wall thickness f is 2mm≤f≤3.5mm, and in automobile interior exterior room, PP material general thickness is within the scope of this.

In the present embodiment, other sizes are as follows:

(1) clamp width a: this size will be asked for according to product size and clamping power.Such as, in this specific embodiment example, clamp width a is 13.5mm.

(2) clamp mounting hole length b:

b＝1.5a≤b≤3a(I)

In formula: b-clamp mounting hole length, a-clamp width.

(3) clamp distortion hole length c:

c＝b≤c≤2b(II)

In formula: c-clamp distortion hole length, b-clamp mounting hole length.

(4) two pitch of holes d, this size is by clamp mounting hole length b size impact, and clamp mounting hole length b size is larger, and this size is larger:

2mm≤d≤7mm(II)

In formula: d-two pitch of holes.

(5) clamp mounting hole width e, according to concrete positioning scenarios, generally value within the scope of this:
